Preheat your oven to 325°F (163°C).
In a mixing bowl, combine graham cracker crumbs, sugar, and melted butter until the mixture resembles wet sand.
Press the mixture evenly into the bottom of a 9-inch springform pan. Use the back of a spoon or a flat-bottomed glass to compact it firmly.
Bake the crust for 10 minutes. Remove from the oven and let it cool completely.
Make the FillingIn a large bowl, beat the softened cream cheese and sugar until smooth and creamy, about 2-3 minutes. Add eggs one at a time, mixing well after each addition.
Stir in vanilla extract, sour cream, and lemon juice. Mix until fully combined, but don’t overmix to avoid incorporating too much air.
Pour the filling over the cooled crust, smoothing the top with a spatula.
Bake the CheesecakeWrap the bottom of the springform pan with aluminum foil to prevent water from seeping in. Place the pan in a larger baking dish and add hot water to the dish until it reaches halfway up the sides of the pan (water bath method ensures even cooking and prevents cracking).
Bake for 50-60 minutes, or until the edges are set and the center is slightly jiggly.
Turn off the oven, crack the door open, and let the cheesecake cool inside for 1 hour.
Prepare the Strawberry ToppingIn a saucepan, combine strawberries, sugar, and cornstarch. Add water and stir until smooth. Cook over medium heat, stirring constantly, until the mixture thickens and becomes glossy (about 5-7 minutes).
Let the topping cool completely before spreading it over the cooled cheesecake.
Chill and ServeRefrigerate the cheesecake for at least 4 hours or overnight. Carefully remove the cheesecake from the springform pan and transfer it to a serving plate.
Slice, serve, and enjoy!
